Thread: Long range fuel tank Disco 4

I am halfway through fitting the LongRanger tank to my D4, and there is an issue.

The tank fits fine, but the change to the filler neck ( for that stupid nozzle blocker ) does mean the filler neck and pipes are different, and those supplied with the tank ( TA62A ) are not compatible. I think LongRanger were looking at the more obvious physical differences, and this one slipped through to the keeper.

I have advised LongRanger, and am currently awaiting a reply.

More data to follow.

Have you had any feedback from Longranger?

They don't believe there is an issue, but they haven't fitted the tank to a D4 themselves as yet. I haven't had the time to revisit the fit, hopefully this weekend.
LongRanger are under the impression the main tank filler pipe is the same diameter as the D3, even though the top of this pipe has a far longer flare on the D4 than the D3.

The hose used as an adaptor is nearly 4mm too big for the filler pipe. I cannot see how that can be squeezed out with a hose clamp.

I will advise further when I get to it.

LongRanger have installed a tank in a D4. They noted my concerns and have indicated that apart from the filler neck flare being longer on the D4 ( to accomodate the misfueling device ), all the pipes and filler are of the same dimensions as on the D3. In essence, if they fit the tank to a D4, the fit is the same as a D3.
-The different size of the filler neck pipe to their adaptor tube, they don't see as an issue.
-The LR fuel cap only just fits. It grabs on about the last 1/4 of the available thread. It is evidently the same as the D3 fit. Any other store bought cap is actually a better fit.
- The wiring is ok if you know where to go for the positive pick up, and can keep the wiring protected and hidden.

So not perfect, but satisfactory. I would add, probably not for the inexperienced . If you decide to go down this path, leave it to those who do this type of work for a living.

I am looking a putting a aux fuel tank in the D4 I would like comment on the best choice 104lts 108lts 120lts
Thanks

I went for the opposite lock tank this time around.

On my previous vehicle the fuel line supplied with the long ranger tank (the pickup line for the fuel transfer) corroded and destroyed the fuel pump....very expensive. Out of town (the manufacturer) was aware that this was a problem, but did not see fit to advise owners.....so decided not to go with them this time.

OL tank gravity fees and has a one way valve so won't flow back to the rear tank.

Been very happy with it.

Was told it was about 90litres, but have got over 105litres into it.

Same filler used, and fills up with a normal pump fast enough. Have not tried a high flow pump yet.

Hi all
Isnt there a tank available which replaces the original tank but with increased capacity.
Cheers

My auxillary tank is the Outback tank supplied by Opposite Lock, I think they said it was 109lts, seems fine so far, it's black, so you don't notice it as much as the others that are painted grey.
